Abstract
PURPOSE: To prevent a secondary flow and improve the performance thereof by a method wherein a protruded wall is provided in the path of flow in a bucket cover fixing a plurality lof moving blades.
CONSTITUTION: A circulating flow path is constituted with the moving blades 1, 2 and the bucket cover 3. The protruded wall 9 is provided at the flow path side of the bucket cover 3. The flow of the fluid in a high-pressure boundary layer 4b, generated at the front side surface 2b of the blade 2, flows through a boundary layer 4c and is intercepted by the protruding wall 9. Thereby, a corner eddy current generated in a low-pressure boundary layer on a back side surface 1a is prevented and thereby preventing the reduction of the performance of the blade due to the loss of the secondary flow. According to such a method above described, the improvement of the performance may be realized.
